SJ-40Concrete multifunctional strength testercharacteristic:
Adopting the principle of "post installation pull-out method" for strength measurement, this principle is the standard test method for testing the compressive strength of concrete in China, which complies with the "Technical Specification for Testing Concrete Strength by Post installation pull-out method" (CECS69:94). When the concrete has a certain strength, it can be tested at any time.
● Comply with the "Inspection Standard for Bonding Strength of Decorative Bricks in Building Engineering" (JGJ110-97) and the "Construction and Acceptance Specification for Exterior Wall Decorative Brick Engineering" (JGJ126-2000).
Many places have established strength measurement curves, and this testing method has been widely used by various quality inspection and testing units and laboratories nationwide.
Each instrument is marked with legal measurement units before leaving the factory and can be used directly. The pressure gauge displays in kN.
The oil circuit is completely built-in, making the appearance simpler. It can avoid the reliability decline and easy damage of instruments caused by external oil pipes, and is an updated product for the current market sales series.
Using our company's newly developed intelligent digital pressure gauge, it has data storage, query, and peak holding functions. It is calibrated using software and does not require disassembling the pressure gauge. When the external force reaches the specified pressure, simply press the "Set" button to complete it. It is one of the few on-site portable detectors on the market that has this function, which greatly facilitates user calibration and use and is highly popular.
